中文摘要: 采用对称不稳定判据,对发生在2001年1月6～7日的一次罕见的山东暴雪天气过程进行了分析,结果表明:暴雪产生在对称不稳定大气中,低空急流促使对流层低层暖湿气流辐合上升,触发对称不稳定能量释放,产生暴雪天气。江淮气旋和暴雪区有向对称不稳定区移动的趋势。
中文关键词: 对称不稳定，低空急流，江淮气旋，暴雪
Abstract:By using symmetry instability criterion,an unusual storm smow appeared on January 6 to 7,2001 in Shandong Province is analysed,the results show that the storm snow occurred in the symmetry instability atmosphere,low-level jet caused warm and humid air converging and ascending in lower troposphere and stimulated the symmetry instability energy releasing and then the event of storm snowfall occurred.The Changjiang-Huaihe cyclone and the region of storm snow moved towards the area of symmetry instability.
